Three Minute Thesis Competition 2023

Hi

I'm Madeleine (Madi or Maddie for short), an Australian astrophysicist interested in globular clusters and all things Milky Way. I was born and raised in Perth, Western Australia, and completed my undergraduate degree and Masters of Astrophysics at the University of Western Australia and the International Centre for Radio Astronomy Research. My Masters thesis, titled Simulating the Formation of Multiple Stellar Populations in Globular Clusters, was supervised by Professor Kenji Bekki. I am currently a PhD candidate at the Australian National University, supervised by Dr. David Yong and Professor Mark Krumholz. I primarily work on high precision spectroscopy and isotopic analysis of globular clusters. Currently I am in my final year of my PhD and am applying for postdoc positions.

My Research

My research interests include:

  • High precision spectroscopy
  • Isotopic analysis
  • Multiple stellar populations in globular clusters
  • Chemical evolution of the Milky Way
  • Galactic archaeology

Publication databases:

My ADS library
OrcID
Google Scholar

Highlights:

1) Isotopic analysis of stars in M22 where I developed code to derive isotopic abundances.

2) High precision differential abundances in M22 where I made the most precice chemical abundance measurements yet in the globular cluster M22 to demonstrate the existence of an iron abundance spread.

3) Simulations of inhomogenity in globular cluster forming giant molecular clouds where I used hydrodynamical simulations to study the extent of possible iron abundance variations in globular cluster forming gas clouds.
